Abstract
A switch includes a repetitive call detection unit which detects a repetitive call which occupies channels in an identical channel group. A release unit releases the channels occupied by the repetitive call when the repetitive call is detected. A restriction unit stores information concerning the repetitive call and imposes a restriction on a connection of a call having information identical to the information concerning the repetitive call. A test unit determines whether a cause of the repetitive call has been removed. A restriction release unit releases the above restriction in accordance with a result of determination by the test unit.
